Find LCM of 816,392,476,609,100 with Prime Factorization
| 2 | 816, 392, 476, 609, 100 |
| 2 | 408, 196, 238, 609, 50 |
| 2 | 204, 98, 119, 609, 25 |
| 3 | 102, 49, 119, 609, 25 |
| 7 | 34, 49, 119, 203, 25 |
| 17 | 34, 7, 17, 29, 25 |
| 2, 7, 1, 29, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 17 x 2 x 7 x 1 x 29 x 25 = 28988400
Therefore, the lowest common multiple of 816,392,476,609,100 is 28988400.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
816 x 392 x 476 x 609 x 100 = 9272577484800
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
609 : 1, 3, 7, 21, 29, 87, 203, 609
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,392,476,609,100, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
392:2x 2x 2x 7x 7
476:2x 2x 7x 17
609:3x 7x 29
100:2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 2x 3x 7x 7x 17 = 319872
Therefore, the value for common factors is 319872.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 9272577484800/(1x319872)
LCM = 9272577484800/319872
LCM = 28988400
Thus, we can understand that the LCM of 816,392,476,609,100 is 28988400.
